About the Launchbox PCB
Launchbox is an open source PCB design by CaelusRocketry, published on GitHub. It is a 2-layer board measuring 137 × 150 mm, with 31 components from 8 distinct parts.
Other key parts include the L7805, HT12E and SerialScrewTerminals. By type, the board carries 18 switches, 6 ICs, 5 resistors, 1 battery holder and 1 diode.
From the project
Source code for our rocket's launch box.
1.) -.lib: Looks like CaelusPCB.lib or Launchbox.lib These are our stable global project libraries, meaning that they are like the framework for all components in all projects
2.) -cache.lib When you copy a project directory, its -cache.lib file is copied with it. If you make changes to the schematic, for example adding a new component, the local -cache.lib file will update. The -cache.lib of the copied project remains the same, and this is how we do version control. You don't need to really know how this process works or why its important. You just need to know that you add components to…
